74
Total consumption of energy from sources outside the Company stood at 13,151 ΤJ from non-renewable energy sources, with electricity accounting for
69.8% of this quantity and the rest representing the consumption of energy from steam. The quantity of primary fuels for the consumption of electricity
cannot be estimated.

Type of significant direct and indirect impacts on biodiversity
Construction or use of industrial plants, mines and transport infrastructures In order to permanently discontinue the disposal of bauxite residues at sea (is a requirement
under the laws), the Ag. Athanassios area had to be landscaped in accordance with the
specifications of the relevant studies. As this meant that the olives trees there had to be
removed, the youngest among them were replanted in Company-owned land.
Pollution
Nil
Introduction of invasive species, pests and pathogenic organisms
Does not apply to ALUMINIUM S.A.
Reduction of species
Concerning sea populations, no differentiation over time is identified, according to studies
by the Hellenic Centre for Marine Research (HCMR). For land populations, no studies have
been carried out recently (the latest one has been included in the Environmental Impact
Study (EIS) 2007.
Preservation of the natural habitat
No
Changes in ecological processes outside the normal differentiation range
(e.g. salinity or changes to aquifer level)
Has not been investigated.
Water consumption
The water required for the production process, and for human activities in the nearby housing settlements is obtained from wells drilled and managed by
ALUMINIUM S.A. in the broader region around the plant, in strict compliance with the provisions of the relevant Decision of the Water Resources Management
Directorate of the Sterea Regional Administration.
The total quantity of water used in the Company’s activities during 2011 stood at 4,536,630 m

, down 0.9% from the corresponding consumption in 2010,
mainly as a result of the reduction by 28% in the quantity of water that the Company purchases from public water supply companies.

Biodiversity
The area where the Company’s plant is located does not form part of any area protected by law nor is it an area of high biodiversity value. The most significant
impact on the environment from the Company’s activities is the disposal of bauxite residues on land (Ag. Athanassios area), while for the time being impacts
on biodiversity have not been investigated by the Company. As regards the rehabilitation of affected areas, the activities for rehabilitation of the 0.018 km
2
limestone quarry area are in step with the progress made in the exploitation of the quarry. Rehabilitated areas are handed over to the competent body (Forest
Department) after completion of the exploitation.
